Know Exactly What Is Inside Your Magento Codebase

It is a structured review of your Magento codebase, custom modules, coding standards, security, core modifications, technical debt and upgrade-readiness. We read the code rather than only running a scanner, because a scanner reports patterns while a reviewer understands intent. You receive a prioritised report of what is fragile, risky or blocking upgrades, with file references for every finding and a remediation roadmap ordered by risk. Typical findings include direct core edits, business logic buried in templates, missing dependency injection, unsafe database queries and abandoned third-party modules. The point is to replace guesswork about the build with an evidence-based picture your team can act on.

A performance audit asks why the store is slow and profiles the runtime: queries, indexers, cache hit rates, frontend assets. A code audit asks how healthy and safe the code itself is, covering quality, security, standards compliance and upgrade-readiness, and it would flag a dangerous database query even if that query happens to be fast today. They overlap, because badly written code is often slow code, but they answer different questions and produce different reports. We offer both. If your symptom is a measurable slowdown, start with the performance audit. If your symptom is fragile releases, fear of touching the code or a stalled upgrade, start here.

By what it could cost you, not by how untidy the code looks. A finding is critical if it exposes customer or payment data, allows unauthorised access, risks data loss, or blocks security patches from being applied at all. Below that sit issues that will cost you money later: core modifications making upgrades expensive, extension conflicts, and code that no longer has an owner. At the bottom are style and convention problems, which we still record but never inflate. Keeping those tiers apart is the whole point, because a report treating a naming convention like an injection risk teaches your team to ignore all of it.

That is common on inherited stores and it does not stop the audit, though it does become one of the findings. We work from a copy taken directly off the server or from a staging snapshot, which is enough to review everything a code audit examines. What is lost is history: without version control nobody can say when a core file was edited, by whom, or why, so we can identify that a change was made but not the reasoning behind it. Getting the codebase into a repository is usually our first recommendation, because until that exists every later improvement is hard to review or reverse.

Yes. Detecting direct core modifications and unsafe overrides is a central part of the audit, and we report the exact files involved. Core edits are one of the most common reasons upgrades break, because the upgrade overwrites the change and the behaviour your business depends on silently disappears, often noticed weeks later in a tax or order edge case. We also flag the subtler version: code that avoids editing core but achieves the same coupling through aggressive rewrites or preferences on classes Magento expects to change. For each one we recommend the supported alternative, usually a plugin, an observer or an extension attribute.

Yes. We review custom code for injection flaws, cross-site scripting, weak input validation, missing access control on admin routes and controllers, unsafe deserialisation, and credentials committed to the repository, then rate each finding by risk so you know what to fix first. We also check your version and patch level against Adobe's published security bulletins, because the most damaging Magento incidents have been unpatched known issues rather than novel exploits. Sansec found roughly 75 percent of stores still unpatched a week after the CosmicSting fix, CVE-2024-34102, and thousands were breached. A code audit is not a penetration test, and we say so plainly.

Yes, and it is one of the most valuable uses of an audit. We flag deprecated APIs, incompatible code and core hacks that will break your next Magento or PHP upgrade, so you begin the project knowing what has to change instead of discovering it halfway through. This matters more as versions age. Magento Open Source 2.4.6 reaches end of support on 11 August 2026, 2.4.7 in April 2027 and 2.4.8 in April 2028, while 2.4.9 arrived in May 2026 on PHP 8.5, with OpenSearch replacing Elasticsearch and Valkey replacing Redis. Those platform changes break assumptions buried in older custom code.

That is one of the most common reasons clients come to us. We map the custom modules, the modifications, the dependency tree and the integration points, then give you an honest, independent picture of the build: what it does, what state it is in, and which parts a new team can safely touch. Inherited stores usually hide two different things, undocumented business rules that exist only in code, and modules nobody can explain the purpose of. We separate them, because removing the second is cheap and misunderstanding the first is expensive. The report doubles as onboarding documentation for whoever maintains the store next.

Yes. We review installed extensions and Composer dependencies for outdated, risky or abandoned packages, and flag modules whose code quality or security is a concern. Extensions are where a great deal of Magento risk actually lives, because they run with full application privileges and their quality varies enormously. We look at how many are installed, whether any are unused but still loading on every request, whether two of them patch the same core behaviour, whether the vendor still ships releases, and whether any have been edited locally, which quietly makes them unupgradable. Where a package is abandoned we say whether it can be replaced, forked or simply removed.

They are welcome to, and the report is written so that they can. Every finding cites the specific file and line involved rather than describing a general concern, so a disagreement becomes a conversation about a concrete piece of code instead of one team's judgement against another's. Sometimes they are right: a pattern that looks wrong in isolation turns out to be a deliberate workaround for a constraint we did not know about, and we record that context and adjust the rating. We would far rather run the walkthrough call and have findings challenged than deliver a document nobody in your team believes.

It depends on how much custom code exists, not on how large the store looks from the front end. A build with a handful of well-structured modules can be reviewed in a few days. A large bespoke codebase with years of accumulated changes, several developers' conventions layered on top of one another, and heavy extension use takes materially longer, because the value here comes from reading the code rather than scanning it. We scope by counting custom modules and lines of custom code first, then agree the depth and timeline in writing before starting, so the work is bounded and the fee is not open-ended.

Very much so, and pre-acquisition is where an audit most obviously pays for itself. It tells you the real state of the code you are taking on: the security exposure, the upgrade blockers, how much of the build is bespoke rather than configured, and the likely cost of the technical debt you would inherit. That last figure is usually the one that moves a negotiation, because remediation effort is a genuine liability that rarely appears in the seller's numbers. We report independently and in writing, and we are content for the findings to be shared with the other side, since an honest audit supports a fair price rather than arguing for one.
